Formulas for holy wrath vs orc / dragon slaying.

In creating my spreadsheet, I noticed that the damage formulas for orc and dragon slaying are identical. Holy wrath has a _nearly_ identical formula which leads to virtually the same result, but not quite. Is this intentional or an oversight? Can I submit a patch to make holy wrath use the same formula?

Orc and Dragon slaying are:
  Code:
special_damage = 1 + random2(3*damage_done/2);


Holy Wrath:
  Code:
special_damage = 1 + (random2(damage_done * 15) / 10);


If damage_done=10:

Orc / Dragon avg= 1 + random2(15)
Holy avg = 1+ random2(150)/10

The two have different results because random2 generates a number from 0 to (value - 1)
Holy is slightly better because it can randomize up to 149, which is essentially 150, while orc/dragon can only randomize up to 14.

I think they are identical. When dividing numbers, if the result is an integer, it's always rounded down. So 149 / 10 = 14. Unifying them into a single function is indeed a good idea.

Is that what it means if a function is initiated as e.g. "int functionname (arguments)"?

If true, I probably have to re-evaluate a lot of the calculations in my spreadsheet...

Yes, it means the function returns an integer. That's why some functions use the scale parameter set to 100, to fix rounding errors. You can use INT() in excel to convert a result to integer for better accuracy.

Re: Formulas for holy wrath vs orc / dragon slaying.

Hmm. I think keeping decimals may still be good for estimating averages. E.g there may be a bonus that will only return 0, 1, 2 or 3, but for estimating average, you are best off with 1.5, and not chopping it to 1.
